no need for mayor’s permit indeed.
i have a different scenario,i have a TIN I applied for and released to me 2 year ago, now i want to put up my own practice,can I use my existing TIN for the purpose of securing my BIR certificate of business registration?

Hi, i will be starting my private practice this month, and im planning to file all the necessary document by january, because the year will come to end na, is it ok for me to put my signage in the clinic even if i dont have the documents yet?
